AS4 – The lightweight solution
Message packaging governed by ebMS 3.0 Support for both push and pull message
exchange choreographies Message security governed by WS-Security Added support for payload compression Support for an AS2-like business-level Non-
Repudiation Receipt (MDN) Reception Awareness – “just enough” reliable
messaging (similar to AS2 and ebMS 2.0) Suitable for SME/lightweight clients
Copyright © OASIS® 2011. All Rights Reserved.
AS4 compared to AS2
AS4 has comparable features to AS2 Push message exchange patterns Support for Non-Repudiation of Receipt signals Support for “lightweight” reliable messaging Support for common security aspects like digital signatures,
encryption Support for payload compression
AS4 additionally supports the features not available in AS2 Message pull operation including support for secure access to
Message Processing Channels Native support for Web Services Support for “lightweight” client implementations

ebXML Messaging 3.0 Part 2: Advanced Features
Copyright © OASIS® 2011. All Rights Reserved.
Extended Concepts & Features
Multi-hop messaging Route messages through a cloud of intermediaries
Message Bundling Send multiple user messages as one SOAP message High volume, non real-time transactions involving
small payloads Message Splitting
Send one large user message as multiple SOAP messages
Large Message Compression Payloads and message headers
Copyright © OASIS® 2011. All Rights Reserved.
Multi-hop – Intermediary Cloud
No direct connection between endpoints End to end secure, reliable routing of
messages across the Cloud Enables connections (store & forward)
between two light clients

Bundle, Split, Compress
Decouple “logical” from “physical” message Many small messages with same destination,
submitted in a short interval, are more efficiently sent as a single ebMS SOAP message bundle
A (very) large message is more effectively sent as a series of smaller message fragments
Reduce data to send by using message compression Applies to large messages and to bundles Also covers message headers
Composes with multi-hop intermediary feature
Copyright © OASIS® 2011. All Rights Reserved.
Bundling Requirements Reduce MSH processing overhead
Transport, security, reliable messaging Both push and pull supported
Consistent Interface Units are still submitted and delivered individually
Configurable Agree on parameters for “compatibility” of units, max
delay, size etc. SOAP pipeline stage
Bundling adds limited complexity to an ebMS 3.0 engine
Bundling composes with other advanced features
Copyright © OASIS® 2011. All Rights Reserved.
Large File Handling in ebMS 3 AS2 Restart feature
HTTP feature rather than AS2 feature Limited to “push”, no support for “pull” mode
AS4 compression Per payload compression
Split, Join, Compress protocol Large message is split by sending MSH and
reassembled by (ultimate) receiving MSH MSHs exchange “fragment” SOAP messages,
controlled by new MessageFragment SOAP header
Optional full message compression feature

Compressed Bundles GDSN Case Study:
23 sample GDSN 2.7 messages, total 306K ebMS3 eb3:UserMessage header info added:
adds 19K (6%) Total after bz2 compression: 13K, i.e. 4%
Other case studies eCom 2.6 order (11 docs, 83K), UBL 2.0 (13 docs,
11.8K), bz2/zlib compression: worst case 8% Comparison with payload compression:
Best case 14%; worst case 25% Use bundle, split and compress to “optimize”
message sizes
